AICHI - A metal screw about 1.5 centimeters long was found inside the mouth of a 4-year-old child having lunch at a kindergarten in Toyota, Aichi Prefecture, city officials said. At around noon on July 27, a childcare worker at Daiko Gakuen Homigaoka Kindergarten noticed that the child's mouth was moving unusually while the child was drinking tofu and bok choy soup. The worker instructed the child to spit out what was in the mouth, revealing the metal screw. Officials believe the screw may have entered the food during the processing or delivery of ingredients, cooking, or serving. Toyota said meals prepared by Tofusu will not be served at the city's childcare facilities until their safety has been confirmed.
